Sounds
These are several files with sounds you can ear on the air. They come from
several sources, the newest modes like PSK31, MT63, QPSK and Hell variants
are from me, others are mainly from Digital
Sounds and from TOR
Sounds - Ham Radio Article . Please note that digital modes may or
may not decode, as they are sometimes compressed.
